（Please place separate orders for each product instead of combining them in a single order.） Still using BOBOVR innovative power swap design, the new battery architecture separates the discharge module from the battery pack, reducing battery pack heat. It also improves the discharge efficiency by 6% compared to the old model, and adds low-battery sound reminders and accurate battery levels. Check; Brand new B100 battery system: Compared with B2, while the volume remains unchanged, the capacity is increased from 5200mah to 10000mah, the battery capacity is increased by 92%, and the weight is only increased by 28%. Thanks to the higher output efficiency, the available capacity is B2 2 times; S3 Pro has a built-in head air-conditioning system, which uses silent technology to keep the head and face cool and comfortable even when Quest3/3S is worn for a long time, and supports 100-level flexible wind speed adjustment; The structure of the back of the head is optimized, and the structure of the back of the head is flatter, allowing you to lie down more comfortably on the sofa (making you sleep more comfortable if you fall asleep). The height of the overhead auxiliary bracket is adjustable and supports personalized removal! Notes: 1. In order to achieve more compatibility in the future, we use an updated battery system, so B2 and B100 cannot work interchangeably; 2. The air conditioning system requires B100 to work; 3. We are about to launch a super charging stand at the end of Q1 2024. The 30w power can allow the B100 to charge 0-80% in one hour. 4. The performance of B100 can still be explored in the future.
